Description

Technical Field

[0001] This utility model belongs to the field of UAV ground station technology, specifically a UAV ground station communication antenna adjustment mechanism. Background Technology

[0002] With the rapid development of drone technology, drones are now widely used in various fields such as aerial surveying, power line inspection, agricultural plant protection, and emergency rescue. As the core control and data interaction hub of the drone system, the stability of the communication link between the drone ground station and the drone directly determines the safety, reliability, and efficiency of drone operations. Furthermore, the ground station communication antenna, as a key device in realizing this communication link, plays a crucial role in the transmission quality of communication signals through precise adjustment of its attitude and position.

[0003] Existing methods mainly focus on adjusting the azimuth angle of the antenna in the horizontal direction or the pitch angle in the vertical plane to meet the signal reception requirements of UAVs in different horizontal orientations or tilted flight attitudes. However, in actual operation scenarios, the flight altitude of UAVs varies significantly depending on the requirements of the operation task (such as high-altitude large-area mapping and low-altitude fine inspection), ranging from tens of meters to thousands of meters. This places dynamic adaptation requirements on the signal coverage altitude range of the ground station communication antenna.

[0004] The core flaw of existing technology lies in its inability to achieve height adjustment of the communication antenna. This limitation directly leads to a series of problems affecting communication performance and operational applicability. Specifically, when a drone performs high-altitude operations, a fixed-altitude antenna cannot concentrate signal energy in the high-altitude communication frequency band, limiting the signal transmission distance and failing to meet the communication needs of long-distance high-altitude operations or adapt to the communication needs of drones at different flight altitudes.

[0005] Therefore, a communication antenna adjustment mechanism for UAV ground stations is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a UAV ground station communication antenna adjustment mechanism, which has the advantages of being able to adjust the antenna according to the flight altitude of the UAV, avoiding the impact on the antenna signal during high-altitude operations due to the high flight altitude of the UAV, and adapting to the communication needs of UAVs at different flight altitudes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a communication antenna adjustment mechanism for a UAV ground station, comprising a ground station body; The surface of the ground station body is equipped with an antenna adjustment assembly, which includes an antenna plate symmetrically and movably connected to one side surface of the ground station body, an antenna body slidably connected inside the antenna plate, and a beveled tooth plate, a blocking strip, and a movable rod for adjustment. The surface of the antenna plate is equipped with auxiliary components, which include a drive rod mounted on the surface of the blocking strip, a support plate symmetrically mounted on the surface of the antenna plate, and an arc-shaped groove, a limiting plate, and a torsion spring for driving.

[0008] Preferably, the two helical toothed plates are symmetrically mounted on the surface of the antenna body, the movable rod is rotatably connected to the outer side of the antenna plate, the blocking strip is mounted on the surface of the movable rod, and the blocking strip meshes with the helical toothed plates.

[0009] Preferably, friction strips are symmetrically inlaid on the outer surface of the antenna body, and the friction strips are in close contact with the inner wall of the antenna plate.

[0010] Preferably, the two support plates are symmetrically mounted on the surface of the antenna plate, both ends of the movable rod are rotatably connected to the inside of the support plates, the arc-shaped groove is formed on the surface of the support plates, and the drive rod is slidably connected to the inside of the arc-shaped groove, and the two limiting discs are respectively mounted on both ends of the drive rod.

[0011] Preferably, the torsion spring is sleeved on the surface of the movable rod, and one end of the torsion spring is connected to the blocking strip, while the other end of the torsion spring is installed inside the support plate.

[0012] Preferably, the limiting plate is located on the outer side of the support plate and fits into the arc-shaped groove.

[0013] Preferably, the arc-shaped groove is based on the center point of the movable rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up an antenna adjustment component, realizes the height adjustment function of the communication antenna of the UAV ground station through the combination structure of antenna plate, antenna body, oblique tooth plate, blocking strip and movable rod. It solves the core defect of the existing mechanism that "cannot adapt to different flight altitudes of UAVs" due to the inability to adjust the height, so that the antenna can flexibly adjust the height according to the operational needs of UAVs from low altitude to high altitude, significantly improving the coverage and stability of the communication link.

[0015] 2. This utility model provides structural support and driving constraints for the antenna adjustment assembly by incorporating auxiliary components, including a drive rod, support plate, arc groove, limiting plate, and torsion spring. The support plate stably supports the rotation of the movable rod and provides overall protection, enhancing the aesthetics of the structure and preventing exposure. The arc groove and limiting plate prevent the drive components from shifting or falling off, while the torsion spring enables component reset, preventing structural loosening or failure during adjustment and ensuring the accuracy and safety of height adjustment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 5 As shown, this utility model provides a communication antenna adjustment mechanism for a UAV ground station, including a ground station body 1; The surface of the ground station body 1 is equipped with an antenna adjustment assembly 2. The antenna adjustment assembly 2 includes an antenna plate 21 symmetrically and movably connected to one side surface of the ground station body 1, an antenna body 22 slidably connected inside the antenna plate 21, and a serrated plate 23, a blocking strip 24, and a movable rod 25 for adjustment. Two slanted toothed plates 23 are symmetrically mounted on the surface of the antenna body 22. A movable rod 25 is rotatably connected to the outer side of the antenna plate 21. A blocking strip 24 is mounted on the surface of the movable rod 25 and engages with the slanted toothed plates 23. Through the combined structure of the antenna plate 21, antenna body 22, slanted toothed plates 23, blocking strip 24, and movable rod 25, the height adjustment function of the UAV ground station communication antenna is realized. This solves the core defect of the existing mechanism that cannot be adjusted due to the inability to adapt to different flight altitudes of the UAV. The antenna can flexibly adjust its height according to the operational needs of the UAV from low altitude to high altitude, significantly improving the coverage and stability of the communication link.

[0020] Friction strips 26 are symmetrically inlaid on the outer side of the antenna body 22. The friction strips 26 are tightly fitted to the inner wall of the antenna plate 21. The friction strips 26 can fill the assembly gap between the antenna body 22 and the inner wall of the antenna plate 21, preventing the antenna body 22 from moving due to the gap during sliding or operation, and greatly improving the stability of the antenna body 22 after adjustment.

[0021] An auxiliary component 3 is mounted on the surface of the antenna plate 21. The auxiliary component 3 includes a drive rod 31 mounted on the surface of the blocking strip 24, a support plate 32 symmetrically mounted on the surface of the antenna plate 21, an arc groove 33 for driving, a limiting plate 34, and a torsion spring 35. Two support plates 32 are symmetrically mounted on the surface of the antenna plate 21. Both ends of the movable rod 25 are rotatably connected to the inside of the support plates 32. An arc-shaped groove 33 is formed on the surface of the support plates 32, and the drive rod 31 is slidably connected to the inside of the arc-shaped groove 33. Two limiting plates 34 are respectively mounted on both ends of the drive rod 31. The design of the drive rod 31, support plates 32, arc-shaped groove 33, limiting plates 34, and torsion spring 35 provides structural support and drive constraint for the antenna adjustment assembly 2. The support plates 32 can stably support the rotation of the movable rod 25 and can protect the overall structure, beautify the overall structure, and prevent it from being exposed. The arc-shaped groove 33 and the limiting plates 34 can prevent the drive components from shifting or falling off. The torsion spring 35 can realize the reset of the components, avoid structural loosening or failure during the adjustment process, and ensure the accuracy and safety of height adjustment.

[0022] The torsion spring 35 is sleeved on the surface of the movable rod 25, and one end of the torsion spring 35 is connected to the blocking bar 24. The other end of the torsion spring 35 is installed inside the support plate 32. When the blocking bar 24 is pushed to rotate by the helical tooth plate 23, the torsion spring 35 will undergo elastic deformation and store reset potential energy. After the external force is released, the torsion spring 35 can quickly drive the blocking bar 24 to reset, so that it re-engages with the helical tooth plate 23 without manual adjustment.

[0023] The limiting plate 34 is located on the outer side of the support plate 32 and fits into the arc groove 33. It can form a radial constraint on the drive rod 31, preventing the drive rod 31 from wobbling radially during sliding, thereby improving the accuracy and comfort of operation.

[0024] The arc-shaped groove 33 is based on the center point of the movable rod 25. The arc-shaped groove 33, based on the center point of the movable rod 25, can make the movement trajectory of the drive rod 31 completely match the rotation trajectory of the blocking bar 24, ensuring the stability of the blocking bar 24 when it rotates around the movable rod 25.

[0025] Among them, the structures such as the ground station main body 1 and the antenna main body 22 are existing technologies, and their working principles are well-known technologies. The appropriate model is selected according to the actual use.

[0026] Working principle and process: When it is necessary to adapt to the higher flight altitude of the UAV and raise the antenna body 22, the operator can directly pull the antenna body 22 upward. At this time, the helical tooth plate 23 on the surface of the antenna body 22 moves upward, and the teeth of the helical tooth plate 23 will generate a pushing force on the blocking strip 24, pushing the blocking strip 24 to rotate around the axis of the movable rod 25 (that is, the blocking strip 24 rotates away from the helical tooth plate 23). During this process, the blocking strip 24 drives the drive rod 31 to slide along the trajectory of the arc groove 33. At the same time, the torsion spring 35 sleeved on the surface of the movable rod 25 undergoes elastic deformation due to the rotation of the blocking strip 24, storing reset potential energy. As the antenna body 22 continues to move upward, the teeth of the helical tooth plate 23 will push the blocking strip 24 to rotate in sequence until the antenna body 22 reaches the required height. At this time, the pulling is stopped, the torsion spring 35 releases the reset potential energy, drives the blocking strip 24 to reset and re-engage with the teeth of the helical tooth plate 23, realizing the height locking of the antenna body 22. For torsion spring 35, SAMINI stainless steel 33-0740 can be considered. This torsion spring 35 is made of stainless steel wire SUS304, which has good corrosion resistance and high strength, and can adapt to the complex outdoor environment that UAV ground stations may face, reducing performance degradation caused by rust or fatigue. From a mechanical performance perspective, it exhibits stability when subjected to the radial torsional torque of the spring coil, which can meet the requirements of the frequent turnover and reset of the blocking strip 24.

[0027] When it is necessary to lower the antenna body 22 to accommodate the lower flight altitude of the drone, the blocking strip 24 is tightly engaged with the helical toothed plate 23 under the action of the torsion spring 35. Its toothed structure forms a one-way limit, preventing the antenna body 22 from moving when pulled downwards directly. At this time, the operator can push the blocking strip 24 along the arc-shaped groove 33 using the drive rod 31, causing the blocking strip 24 to overcome the restoring force of the torsion spring 35 and rotate around the movable rod 25 until the blocking strip 24 disengages from the helical toothed plate 23. In this state, the antenna body 22 can be slowly pushed downwards. After adjusting to the target altitude, the drive rod 31 is released, and the torsion spring 35 drives the blocking strip 24 to reset and re-engage with the helical toothed plate 23, completing the altitude lock.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
